Pre- & Glassmastering is one of the most sensitive technologies in the audio CD production. This is the last station, where the sound quality of the final product is still a decisive influence, which happens with the use of SDG technology.
Given the ambitious targets audio edit data without quality loss none of the mastering equipment available on the market are attainable, SDG has built is own facility. It has created a special computer, which applies principles, elements and materials for future electronics and computer techniques.
In the pre-mastering phase, when the company SDG digital audio master, the obligatory DDP (Disc Description Protocol)-Image File undergo conversion, which in this distortion and low noise levels is carried out jitter SDG special-purpose computer.Then, for glass mastering the encoder to the EFM (Eight to Fourteen Modulation) for CD, DVD or ETM (Eight to Twelve Modulation) for Blu-ray Disc converted signal is filtered again, then written into the laser beam recorder on glass illuminated (Calcined ). The electronics for signal conversion and laser control technology is also SDG-master is burned to the signals in the form of an ultra-clean square wave signal on the glass. Then the metallized glass master is developed and galvanized.
Recently it has become possible with direct-to-Glass mastering by our mastering facility produced extremely clean signal to implement physically.
With the directly into the tempered glass discs etched pits, it is possible to produce grown in the pits for the optimal sampling rectangular shape. Thus the benefits of technology come with sharp edges and high slope even better coverage. The laser light reaches the photodiode steeper slopes in the output signal.
The pit structure achieved with this technology is so clean that the player can read them without a reflective layer. Only the intensity of the laser needs to be readjusted, what most players are able to do for themselves. This is especially important for long-term archiving, which can be dispensed by the reflective layer and the protective lacquer. So we can just use the glass discs. Of course, the gold-coated "traditional version is" still to choose from.
This product is the first and only media in the world, who holds up forever, "as carved into the stone."All magnetic data storage systems such as hard disks and magnetic tapes can be compared to our solution only for temporary use will be considered suitable. Most only as a backup but not as long-term archiving.
Therefore, globally, many libraries, computer centres, state and provincial archives, radio and television stations on our glass discs especially happy. The vast archives of film, video, tape or microfilm records and archives can be replaced with an unlimited durable medium, certainly saved.
Gone are the days when you had to just copy everything over again, where a fire, water or electricity damage could destroy valuable documents. Our glass discs must be done only once and accessibility, network or broadcast capability, and forgery are secured forever.
A medium is the passive, requires no maintenance, no electricity, or cooling, heat, cold, acid resistant, and completely without costs.
In the manufacture of the stamper, the feedback and requests for fine-tuning and optimisation are widely considered the in tandem working Pressing Plant companies KSP and NOD. There are then ready pressed onto disks, printed and undergo a final quality control. The discs are now meeting our quality requirements, will be packaged and delivered to the client.
Mastering is the real fine-tuning to get out of the recording after the mixdown its maximum. This is usually done in mastering studios that are directly assigned to the target.
In addition to optimal listening conditions, the mastering engineer has an arsenal of equipment, the sound edit, modify and convert. It would be a very long list if we wanted to mention all the methods of equalization and normalization, of dynamic compression until the echo effects. There are those that are used in the digital domain, but also those who work on an analog basis, or even with tube technology.
The virtue of mastering engineers is to make the right decision, what corrections are necessary to achieve the best possible sound. By this plays musical and technical education, training, personal experience and taste, but often also fashions a very important role.
But it remains an obstacle that is insurmountable: the current state of the art. The available on the market and equipment used here are often built on false principles, and price calculations. The thing has a history that has begun with cheap digital converters, then its disadvantages had corrected with more and more aggressive countermeasures.
The symptoms are persistent and accumulate. The corrections made with the best will turn out later to be exaggerated, even false.The result is a dull and pulpy sound. Interpreters can often recognize their own records hardly.
The SDG-Mastering facility has not these symptoms, therefore it does not rely on the counter. The technical superiority, which is on pre-and Glassmastering there is also the mastering of the best. We have therefore taken the decision to offer with the use of the plant even Audio mastering. We are in a position to restrict the sonic parameters of the basic necessities or to limit the negative consequences.
In this context, we also want to work with recording and mastering studios, and help to deal with the new perspectives, to use their skills accordingly effective.
It does not matter what technique is used for recording from analog tube technology to purist R2R PCM, high-resolution multibit sigma-delta, or DSD, from 2 channel to multi-channel.
The recordings are, however, in all CD players in plain stereo, without additional electronics, decoding, or any other restriction be playable. We ask in addition to the recordings (on CD-R or DVD-R) to send information about the use of technology, equipment and methods. Reason: Our SDG-master technique allows a very transparent sound with low distortion. This is also the disadvantages of possibly exaggerated corrections strongly audible. Since the consultation will be necessary. Consumer abuses that restrict the user, injure, or spy, we reject categorically.
